WICK TUBE AND RAISER FOR OlL-STOVES.

SPECIFICATION forming part of Letters Patent No. 304,985, datedSeptember 9, 1884.

Application filed February 15, 1884. (No model.)

To all whom it may concern.-

Be it known that I, LEWIS J .-Arwoon, of Waterbury, in the State ofConnecticut, have invented an Improvement in Wick Tubes and Raisers forOil-Stoves, of which the following is aspecification.

In ordinary lamp-burners the wick has been raised by means of tworollers, one at each side of the wick, and there have in some cases beendisks opposite to the wick-raising wheels to lessen friction.

My present invention relates to the wicktube for an oil-stove, in whichthe two sides of the. wick-tube are made alike, each one having a recessor housing that is struck up in the metal of the wick-tube, and Icombine with these a wick-raising shaft and wheels such as have beenseparately used, and a roller within the housing at the opposite side ofthe wick-tube, whereby the friction and force required to raise or lowerthe wick are materially lessened, and the roller serves to guide thebroad wick at one side through and prevent the same becoming misplacedor bent into an irregular condition, thereby insuring uniformity in thewick throughout the entire length of its upper end.

In the drawings, Figure 1 is a vertical section of the wick-tube andwick-raisers, and Fig.2 is a sectional plan at the line :0 w.

The side plates, a b, of the wick-tube are made with return-lips c atthe ends, which interlock together and are soldered. In each side platethere is a long deep recess or cavity formed by pressing the sheet metalbetween dies. This recess is rather deeper than a half-circlesectionally, and there are openings at the ends for the reception of thebearings e e, c, and f. The bearings e e are tubular with closed ends.The bearing f is an open tube. All the bearings are soldered into place.

The wick-raising wheels 9 g are upon the shaft h, which shaft passesthrough the open bearing f, and the end is received into the closedbearing 6. There is a thumb or hand wheel, k, at the outer end of theshaft h, by which the shaft and wick-raisers can be rotated in raisingor lowering the wick.

The roller Z is provided with pivots 0 at its ends entering the tubularbearings e c. This roller Z is within the recess or housing in the sidea of the wick-tube, and it forms a guide to the wick and keeps it fiatand properly in place, and lessensfriction as the wick-raisers act uponthe wick to move the same.

The tubular bearings e e c f form reliable supports for the respectiveshafts or pivots, and they wear longer and create less friction than theshect-metal edge of the housing heretofore made use of.

I remark that the roller and the wickraisers and wheels will usually beput into their respective places before the two halves a b of thewick-tube are put together and sol- (lered.

I do not herein lay claim to any of the separate portions of thewiclctube nor to any of the devices set forth in my application filedFebruary 10,1882, Serial No. 52,311, and in application filed January32, 1882, Serial No. 49,937.

I claim as my invention- 1. The combination, in a wick-tube foroilstoves, of two separate side pieces, a I), each of which is providedwith a housing struck up in the sheet metal, a shaft, wick-raisingwheels, and a thumb-wheel on such shaft, and a roller in the recessopposite to the wickraisers, such roller extending nearly the length ofthe recess and guiding the wick, substantially as set forth.

2. A wick-tube made of two plates clasped together at the ends, eachhaving a deep recessed housing, in combination with the wickraisin'gshaft and wheels, and a rollerand separate tubular bearings introducedinto holes at the. ends of the housings and secured in place,substantially as set forth.

Signed by me this 8th day of February, A. D. 1884.
